IRVING M. SCOTT, OF SAN FRANOISCO, GALIFORNIA.

FLANGE CONNECTlON.

SPECIFICATION formng' part of Letters Patent No. 245,403, dated August 9, 1881.

Application filed May 19, 1881.

To all whom it may concew:

Be it known that I, IRVING M. Scorr, of the city and county of San Francisco, State of California, have invented an Improvement in I`lange-Counectious; and I hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to an improved langeconnection forjoining the ends ot' pipes; and it consists in providing the ends ot' the pipes with pemliarly-shaped flanges and securing' them with peeuliarly-shaped bolts, all of which will hereinat'ter be more luliy explained.

Ppes ae ord'narily connected by bolts driven through simple fianges, and the boltholes in each have to correspond. This is inconvenient when a length ot' pipe has to be connected with one already in place, because its position ay render it impossible to make the bolt-holes correspond.

The object ot' my invention is to provide such an intermediate connection as will permit the pipes to be easilyjoined in whatever position desirable.

Referring to the aceompanying drawings, Figure l is a horizontal section. Fig. 2 is a vertical section.

Let A reprcsent one section of a pipe, and B another. The pipe A is provided ou one end with a cup-shaped fiange, O-that is, one eX- tending outwardly and turned theuce at right angles downwardly. The pipe B is provided on one end with a simple projecting fiange, D, said fiange being narrower than the cxtended portion ot' the flange C. These two fianges are fitted together. The nppcr tlange is provided with holes a.

E represents bolts. They are provided with screw-threads on one end, and have on the other end a hook or lug, c, projecting at right angles. The flangc 1) not being as wide as the fiange C, a space is left between its edge and the downwardly-turned portion of the flange G. Through this space the bolts E are passed from below, their screw-heads passing through the apertures a in the fiange G, and are pro- Vided with nuts F on top of the said flange.

(No model.)

They are then turned so that their lugs c will be turned toward the pipe and fit under the flange D. By tightening up the nuts F the bolts will draw the two fianges tightly together and form a close connection. The bolts, when tightened, will not slip or turn from their positions.

By const'uuting the different sections otpipe with corresponding flanges, such as are herein described, any length of pipe may be made.

The pipes can he readily disconnected by loosening the nuts F and turning the hook c on the bolts from under the fiange D.

This form ot' connection will allow the length of pipe to be carried to any position and connected at any angle with pipes already in place, because either joint can be turned on the other to make the pipe fit the proper connection.

l am aware that, broadly, the use ol' h0ok bolts Secured to one flange and adapted to be hooked overthe other ahutting tlange are old, and such device= broadly, I do not claim but by my specific arrangement I obtain a joint that is guarded against any accidental displacement by the use of an clongated fiange coverng the hooked portions of the bolts.

Having thus described my invention, what I claim as new, and desire to secure by Let-ters Patent, is

A means for eonnecting and adjnsting the meeting ends ot' pipe-joints, consisting ot' the perforated cup -shaped fiange 0, projecting from one of the sections, so as to overlap the narrower fiange D of the other section, in combination with the hook-bolts E, whereby the book-bolts may be turned so as to bind against the fiange D and lie fiush or countersuuk within the projecting fiange C, thereby preventing said hook-bolts from working loose through accident or otherwise.

In witness whereof l have hereunto set my hand.

IRVING M. SOOTT.
